0017 Description
0018 -----------
0019
0020 This driver supports hardware monitoring for Maxim MAX16064 Quad Power-Supply
0021 Controller with Active-Voltage Output Control and PMBus Interface.
0022
0023 The driver is a client driver to the core PMBus driver.
0024 Please see Documentation/hwmon/pmbus.rst for details on PMBus client drivers.
0025
0026
0027 Usage Notes
0028 -----------
0029
0030 This driver does not auto-detect devices. You will have to instantiate the
0031 devices explicitly. Please see Documentation/i2c/instantiating-devices.rst for
0032 details.

0045 attributes are read-only.
0046
0047 ======================= ========================================================
0048 in[1-4]_label "vout[1-4]"
0049 in[1-4]_input Measured voltage. From READ_VOUT register.
0050 in[1-4]_min Minimum Voltage. From VOUT_UV_WARN_LIMIT register.
0051 in[1-4]_max Maximum voltage. From VOUT_OV_WARN_LIMIT register.
0052 in[1-4]_lcrit Critical minimum Voltage. VOUT_UV_FAULT_LIMIT register.
0053 in[1-4]_crit Critical maximum voltage. From VOUT_OV_FAULT_LIMIT
0054 register.
0055 in[1-4]_min_alarm Voltage low alarm. From VOLTAGE_UV_WARNING status.
0056 in[1-4]_max_alarm Voltage high alarm. From VOLTAGE_OV_WARNING status.
0057 in[1-4]_lcrit_alarm Voltage critical low alarm. From VOLTAGE_UV_FAULT
0058 status.
0059 in[1-4]_crit_alarm Voltage critical high alarm. From VOLTAGE_OV_FAULT
0060 status.
0061 in[1-4]_highest Historical maximum voltage.
0062 in[1-4]_reset_history Write any value to reset history.
0063
0064 temp1_input Measured temperature. From READ_TEMPERATURE_1 register.
0065 temp1_max Maximum temperature. From OT_WARN_LIMIT register.
0066 temp1_crit Critical high temperature. From OT_FAULT_LIMIT register.
0067 temp1_max_alarm Chip temperature high alarm. Set by comparing
0068 READ_TEMPERATURE_1 with OT_WARN_LIMIT if TEMP_OT_WARNING
0069 status is set.
0070 temp1_crit_alarm Chip temperature critical high alarm. Set by comparing
0071 READ_TEMPERATURE_1 with OT_FAULT_LIMIT if TEMP_OT_FAULT
0072 status is set.
0073 temp1_highest Historical maximum temperature.
0074 temp1_reset_history Write any value to reset history.
